How To Enable Resizable Bar Gigabyte?

How to Enable Resizable BAR on Gigabyte Motherboards

Resizable BAR, or Base Address Register Remapping, is a new technology that can improve the performance of some games by up to 15%. It works by allowing the CPU to access the entire graphics card memory at once, rather than having to access it in smaller chunks. This can improve performance in games that are heavily dependent on the CPU, such as Battlefield and Call of Duty.

Enabling Resizable BAR is relatively simple, but it does require a compatible motherboard and graphics card. To check if your motherboard supports Resizable BAR, you can consult the manufacturer’s website. To check if your graphics card supports Resizable BAR, you can look for the “Resizable BAR” or “ReBAR” logo on the product packaging or in the product specifications.

Once you have confirmed that your motherboard and graphics card support Resizable BAR, you can enable it by following these steps:

1. Open the BIOS.
2. Navigate to the “Advanced” or “OC” tab.
3. Look for the “Resizable BAR” or “ReBAR” setting.
4. Enable the setting.
5. Save and exit the BIOS.

That’s it! You have now enabled Resizable BAR on your Gigabyte motherboard. To test if Resizable BAR is working, you can run a benchmark test such as 3DMark. You should see a performance improvement in games that support Resizable BAR.

Resizable BAR, also known as ReBAR or AMD Smart Access Memory, is a new feature that allows the CPU to access the entire GPU memory. This can improve performance in some games by up to 15%. However, Resizable BAR is only available on certain GPUs and motherboards.

In this guide, we will show you how to check if your system supports Resizable BAR and how to enable it if it does.

What is Resizable BAR?

Traditionally, the CPU has only been able to access a small portion of the GPU memory. This is because the CPU and GPU communicate using a separate bus called the PCIe bus. The PCIe bus has a limited bandwidth, so it can only handle a certain amount of data at a time.

Resizable BAR allows the CPU to access the entire GPU memory by using a different bus called the Infinity Fabric. The Infinity Fabric is much faster than the PCIe bus, so it can handle more data at a time. This allows the CPU to access more data from the GPU memory, which can improve performance in some games.

How to check if your system supports Resizable BAR?

There are a few ways to check if your system supports Resizable BAR.

  • Check your motherboard’s manual or website. Your motherboard’s manual or website should list the features that are supported by your motherboard. If your motherboard supports Resizable BAR, it will be listed in the manual or on the website.
  • Check the specifications of your GPU. The specifications of your GPU should list the features that are supported by your GPU. If your GPU supports Resizable BAR, it will be listed in the specifications.
  • Run the Resizable BAR test in GPU-Z.** GPU-Z is a free utility that can be used to check the specifications of your GPU. It also has a test that can be used to check if your GPU supports Resizable BAR.
